Cloudflare DNS

Leverage Cloudflare’s global network to deliver excellent performance and reliability to your domain.

Available on all plans

Cloudflare DNS is a fast, resilient and easy-to-manage authoritative DNS service. It delivers excellent performance and reliability to your domain while also protecting your business from DDoS attacks and route leaks and hijacking.

Features

DNSSEC

DNS Security Extensions (DNSSEC) adds cryptographic signatures to your DNS records, preventing anyone else from redirecting traffic intended for your domain.

Cloudflare also supports Multi-signer DNSSEC.

CNAME flattening

CNAME flattening delivers better performance and allows you to add a CNAME record at your apex domain (example.com). Paid accounts can choose to flatten all CNAME records on their domain.

Use CNAME flattening

Refer to DNS features and availability for a complete list of features and their availability according to different Cloudflare plans.
